Hi,
Some providers will delegate a classless reverse lookup zone to you. That's
what you expected.
Some providers will NOT delegate the zone to you - instead they have THEIR
name server act as secondary to your master name server for that zone,
i.e., they do zone transfers from your master
The customer's CIDR Block: 65.69.21.192/27
Zone in my NS: 192/27.21.69.65.in-addr.arpa (this is from the SimpleDNS
Plus reverse zone wizard)
Mail server: smtp.gbltx.com [65.69.201.195]
If I nslookup 65.69.201.195, all is fine, if I nslookup
195.201.69.65.in-addr.arpa, it only lists NS records

swbell isn't delegating authority
I typoed, it is 65.69.201.192/27, and my zone is
192/27.201.69.65.in-addr.arpa.
Actually, the swbell servers are just sending the request to your DNS
servers, so DNS clients will look up 192.201.69.65.in-addr.arpa (without
using any CNAMEs). Your DNS server is not returning any answers for

For some reason I wasn't catching that they were referring to a zone
named 192.201.69.65.in-addr.arpa instead of
192/27.201.69.65.in-addr.arpa as I had it. All works now. I guess I was
expecting my server to need the CIDR notation to know that it needs to
find the delegating server for the rest
